Newbie looking for some guidance

Hello fellow members of XDA,
I am new to this whole thing of rooting and installing custom rom, so I’m kind of overwhelmed. I have done some poking around prior to this post and stumbled upon the Sticky and was wondering if the “[REF] [GUIDE] Welcome to your device, the Galaxy S III - by theexel” is this the standard to what I should be following?
I have a T999 on 4.1.2. I appreciate your time, recommendations, and advice that you have to offer. Thanks!
Update:
I was hoping you could answer some questions I have for Sanranhai's stockMod 4.3. If i followed the instructions while flashing the rom + one of the modems I'm still able to go back to older roms correct? Also if i decided to cmw restore to my backup (4.1.2 image) will the modem be the one I flashed from saranhai's or will it go back to how it originally was before? Thank you for your time.

Yes that's a Good Guide. What do you intend or trying to do ?

My intention was to root, and to flash a stable rom (hopefully 4.3) for daily use, getting rid of some bloatware to speed up my phone, getting a new feel and look for me phone and increase battery life if possible. I know my model is receiving the official 4.3 but according to this forum most people don't like what Samsung did to it. Since I'm still in the earlier software version, I thought I'd give custom roms' a try.

If you are looking for a pretty good stable 4.3 ROM I'd recommend Saranhai's StockMOD 4.3 .. I used it as my DD (Daily Driver) the past month but have been on Doc's 4.3 ROM before that (they both use the same Base and Doc had to stop because he Bricked his S3 fiddling around with new things).. .. I wouldn't recommend doing the Official 4.3 Update, many people updated and the problem is you can NOT downgrade firmware afterwards, yes flash other 4.3 Roms but no downgrading.. Also the whole Warranty Bit isn't attractive to people.. ... Last night I flashed CM11 4.4.1 (KitKat) and been using it since then. So far I am very happy with it, everything that I MYSELF use daily hasn't had any flaws. Batter life has been decent also but their have been mixed results.. If you're gonna take the leap into rooting/flashing just remember to always read the OP's instructions as well as make sure its for YOUR device (ie: T999, T999L, etc).. Reading and educating yourself is key!

I'll give rooting a try after I'm done with finals. What sort of things do i need to backup for safety measures as that guide isn't very detailed in that aspect of how to do it and what I WILL WANT to backup.

You are not at risk of loosing the Data. But if you feel like it, please mae sure your contacts are successfully synced to Google. If there are Games whose progress or score you want to back up then do that. Apart from that the usual pictures and music stuff.
Try My Backup app. It will let you make a backup even if you are not rooted.

One more thing you do is to move all your required data like photos etc to your ext sdcard as 4.2 and above version will create a folder 0 where your new data will be available

So Im assuming I have to root first before I can install a rom. According to the sticky guide I should be following this http://forum.xda-developers.com/showthread.php?t=1771687 but, there's a note in bold that said "Do not flash a prior release after flashing this, it has been reported to cause bricks, read the thread for more information." Does that mean after using that latest version to root my t-999 i cant go back to older roms?
The guide also recommend i should start with 4.0.4 roms, should i ignore that?

You assume correct. You need to root first. Take the Guide advice. Do not Try to flash latest 4.3 version of Root66. Use the 4.2 version instead. So long you stay completely away from Samsung's release of 4.3, you will do fine.

Why should one stay away from Doc's 4.3 version of Root66?
Does this advice apply equally to saranhai's StockMOD?

You can use Doc's Leaked Rom or Saranhai's StockMod just fine. No issues there. Only thing you should remember, is that if you use the Root66 4.3, it will update your Bootloader to UVUEMJC. If that happens, you will never be able to flash previous bootloaders or previous Root66 versions. In addition, this new bootloader introduces eFuse and a new Warranty Counter. Those can not be reset once tripped.

You are right. Slip for me. I meant the UVDMD5 version which is 4.1.2. Yes you can flash any 4.3 Roms custom or otherwise. If you wish you can follow DocHoliday's Rooted Stock 4.3 Rom.
Samsung 4.3 is Official OTA that's correct.

So i've managed to root my s3 as well as install CMW, backup (took a while to figure out) and restore. <-- this is the NANDROID people are talking about right?
I am ready to take the next step now in playing with custom roms, however, I must first ask if there are any suggested guides I should read prior?

[Q] Gs3 back to stock help

I'm totally new here, and I need help. I have installed cm11 on my GS3 because the stock 4.3 OTA had terrible battery life. I tried flashing back with odin and it didn't work, I want to go back to stock only because of the 4.4 Kitkat update that should be coming "soon". I am afraid of bricking my device and odin keeps giving me a fail (auth) error :crying::crying::crying:. This is extremely frustrating and I hope you guys can save me. How can I get back to stock without bricking my device?

Are you using an AT&T s3? You're probably getting the failure in Odin because you have a 4.3 bootloader and the ROM you're flashing may be trying to downgrade the bootloader.

Yes, sorry i forgot to specify that I am indeed using an AT&T s3. So if I get the actual 4.3 rom and attempt to flash it, it should work? I just realized the rom I was attempting to flash was 4.1.1. I am just not with it today.

You could try, but it recommends starting from a stock ROM or stock-based ROM.
Alternatively, you could flash another custom KK ROM for now and load a custom KK ROM that's based on the official release in the future.
The Valudis and Cyanfox ROMs are supposed to be quite good for battery life.

[Q] Galaxy S3 custom rom question?

Okay so my cousin has a galaxy s3 from at&t running 4.1.2 or 4.1.1? forgot, touchwiz and rooted, is it safe to install a kitkat aosp rom without updating to 4.3 jellybean touchwiz and removing the knox on that then installing the custom rom?

Yes, you can install a kitkat based custom ROM without necessarily first updating to 4.3JB. The custom ROM would probably, like most custom ROMs do, retain your current bootloader. Whether or not it's safe to do that would depend on what ROM you are flashing. There is always a risk in any custom ROM and you would need to do your research thoroughly prior to proceeding.

So what rom would be a bad one with 4.1.? Of course flashing a rom that is not for our phone, but is there anything we should look out for when running roms with 4.1?

I'd be wary about custom ROMs for several reasons. No easier way to brick or backdoor your phone so you'd need to do a lot of research. Making recommendations or criticisms would be against the rules of the forum so I cant really make direct references. Generally, however, you should avoid any rom that messes with your bootloader. Also, unless you are a developer or tester gathering development data, you'd do well to stick with stable versions and avoid nightlies. Finally, the well known and tested names are usually safer and have better user support.

Oh man My phone just came it it's running on MJB but it rooted. Now I have to figure out what is safe to run on that. Man I thought this phone would be easy to install roms but it's seems way more tricky than most phones at least with the MJB bootloader. I really just want my acid sound mod.

You can still run a custom ROM with the MJB bootloader especially since it is rooted and probably de-knoxed already. Most custom ROMs don't dicker with your bootloader. In fact, I don't know of any which does. I have, however, heard several reports that some of them do muck with your bootloader which is why you need to proceed with caution.

does this mean that you can flash any other custom rom even if tis base on 4.3 and lower version?

Yes. Custom roms generally only include the system and kernel, so your base firmware would remain at 4.4.2.
If you go too old though, such as flashing 4.0.4 or 4.1.1 roms, theres no guarantee they wont be a bit buggy. But they should still run nonetheless.
The thing to keep in mind though, is it is ok to flash older roms, kernels and recoveries, but nothing else.

[Q] Atempting to remove Knox from firmware befor update.

I have a T-mobile Galaxy S4, SGH-M919 running android 4.2.2 and want to upgrade to android 4.3. Okay my question is can I remove knox from the update before updating? I HATE KNOX. I saw where over at s4 mini archive they showed a way that they say it can be removed. Any ideas? Anyone tried this? Any other ways to remove??? Any help would be great. I am sorry if this has been posted or asked before, I have not seen it. http://www.s4miniarchive.com/2013/12/how-to-remove-knox-bootloader-from-new.html

Just use this. http://forum.xda-developers.com/showthread.php?t=2544612 and install a custom rom. Any reason why you want 4.3? You can install 4.4.4 which just came out. Remember to just flash modem only and not the lte modem or you will break sound. If you want to stay completely stock and not have Knox there is no way.

+1 on custom rom. Something like this: http://forum.xda-developers.com/showthread.php?t=2876946

Sorry been a little busy. I'm currently using the MDL bootloader, no knox. I hear there is performance and feature advantage to updating to a newer bootloader. The reason I am looking at 4.3 is that some people have stated that you can remove knox from the bootloader in 4.3. The people stated that they have been able to do this to the S4 mini's 4.3 bootloader. I have looked at the links you two have given me, thank you. What bootloaders are you two using? Also have you seen this as this is what got me thinking. http://forum.xda-developers.com/showthread.php?t=2549357

Bootloader has nothing directly to do with performance. Be careful what you read.

True. But I would prefer to be 100% knox free. So not just a knox free rom, but the bootloader as well. Staying on android 4.2.2 will do that but at the same time I would like to upgrade to a newer android version. I have seen some nice custom roms with nice performance, but they are 4.3 and newer. And this is why I am looking.

You can keep MDL boot loader, and flash 4.3, 4.4.2, or 4.4.4 ROMs no problem. I've got an M919 with MDL boot loader and am currently running Dirty Unicorns (4.4.4-based) ROM.
I've got all the benefit of the latest version of Android (plus many customizations!) and no Knox.
The only think that you can't do on the MDL boot loader is run a newer LTE modem... the LTE modem (non-hlos.bin) is tied to the boot loader. However the GSM modem (modem.bin) is not, so you can update that part of it. It's something to keep in mind, but the LTE modem in MDL is fine and works for me quite well even in marginal signal areas.

Yes, it's based off AOSP. See the Samsung home page for Dirty Unicorns here. Also the G+ Community for it.
If you are looking for a TW ROM, I had a great experience with GoldenEye v. 38 over the summer. Very stable, and everything worked, even on my ATT version S4 I337 using SafeStrap. I got sick of SafeStrap limitations and eventually bought a M919 so I could do anything I wanted ROM wise... but GoldenEye was very nice. Debloated, very stable, felt good.
Being very satisfied with my current version of Dirty Unicorns, I'll probably not change any time soon, thought I've been tempted to install SlimKat and build up the features I want. I use SlimKat on a tablet, and like it's very light footprint. Quite zippy.

Just something to remember: Bootloaders (all the bad KNOX junk) CANNOT be flashed via custom recovery. So if you are flashing a stock ROM (firmware?) via custom recovery you will NOT get KNOX. If, however you decide to flash a ROM/firmware via Odin chances are very good that you will be getting a new bootloader and all the KNOX garbage it brings.
TLR
If you flash via recovery you won't get KNOX, if you flash via Odin you probably will.
Modems must also be flashed in Odin, but as far as KNOX goes, it's the bootloader you don't want.

Okay, does this mean I have knox or do not have knox.

No Knox there.
You would see a Knox warranty line in that bootloader screen if you had it.

Cool, so it worked.

Yes, what I'm saying has been tested and confirmed 100%. There is no way to flash a KNOX-implemented bootloader (or ANY bootloader for that matter) via custom recovery. You seem to have the misconception that the KNOX apps within the ROM is what all the KNOX talk is about. If anything, it's only a small part. Now, I'm not absolutely certain of how this works as I've only followed the technical posts in the Development only forum regarding this for the first 10 or so pages, so if I say something that isn't exactly accurate, please forgive me. The basic gist is that when you hear about KNOX and why it's not necessarily wanted in the updated firmwares isn't because of a few user-removable apps; it's something at the hardware level that, when during the boot up tests and checks, it notices that there is a custom kernel or custom recovery in place instead of the expected stock kernel/recovery, it blows an e-fuse and forever after tells anyone who looks at the download mode that the device has been modified at one point or another.
About the random restarts, without knowing whether you updated from 4.3 to 4.4.4 via custom recovery or other official means, all I can say is to try a factory reset and/or use Odin to re-flash the firmware and do a factory reset after that.

Yes, what I'm saying has been tested and confirmed 100%. There is no way to flash a KNOX-implemented bootloader (or ANY bootloader for that matter) via custom recovery. You seem to have the misconception that the KNOX apps within the ROM is what all the KNOX talk is about. If anything, it's only a small part.

Okay, I misunderstood on what you said could be flashed, but will have to take a look. Could you please point me in the right direction for that forum. As far as the misconception goes I do know that KNOX is in the bootloader. I also know that KNOX app/software is found in the rom as well. As for KNOX being in the rom Titanium Backup helps to remove most of it. Or I can just installing a custom rom that has it removed. The main reason that I had started this forum was to remove the KNOX from the bootloader. The reason I pointed to http://www.s4miniarchive.com/2013/12/how-to-remove-knox-bootloader-from-new.html in the first post is because they stated it could be done. After doing some other looking around and talking to others I tried it. Seems like it works on android 4.3, but 4.4.2 and 4.4.4. when I try to do the same it is not happy. I updated via Odin. The first time was 4.2 to 4.3 after modding the bootloader and not the rom. It works fine no KNOX lines in download mode. Still KNOX in the rom but uninstalled using Titanium Backup. Currently I am running android 4.3 on my Galaxy S4 no issues and as far as I can tell no KNOX.

Wait.... your on 4.3 or 4.2 and have been able to unlock the bootloader on them?? Everything you said above is exactly what I have seen and heard also with the addition that the signatures not matching verification checks are what is blowing the q fuse or what Knox and the Samsung / att security freak out about right?

I was on 4.2 and downloaded the stock 4.3 to my Linux pc. I then did what was stated on the s4 mini forums and was able to remove Knox from the bootloader, then the rom via titanium backup. Note as far as I know you can't remove Knox once it is already there.
